IIC/I2C Serial Interface Adapter Module

From the shop's description

IIC/I2C Serial Interface Adapter Module Due to limited pin resources in a microcontroller/microprocessor, controlling an LCD panel could be tedious. Serial to Parallel adapters such as the I2C serial interface adapter module with PCF8574 chip makes the work easy with just two pins. The serial interface adapter can be connected to a 16×2 LCD and provides two signal output pins (SDA and SCL) which can be used to communicate with an MCU/MPU. ? Features: This section mentions some of the features and specifications of the I2C Serial Interface Adapter Module. Operating Voltage: 5V DC I2C control using PCF8574 Can have 8 modules on a single I2C bus I2C Address: 0X20~0X27 (the original address is 0X20, you can change it yourself via the onboard jumper pins) Pin Configuration: The module has multiple pins onboard for communication with the MCU/MPU via the I2C protocol. The table below shows the pin name, type, and their functions.
